Answer:
A
Step-by-step explanation:
subtract 5 from all parts to get
-15 < 3x < 21
Divide each part by 3 to get
-5 < x < 7
Answer:
a) The value of If(i)I = √2.
Step-by-step explanation:
Here the given function is f(x) = 1 - x
To Find: If(i)I
First;y, let us find the value of f(i).
Substituting x = i in f(x) , we get:
f(i) = 1- i
Now, The modulus value of a function P = A + B is written as :
So, here calculating the value of If(i)I :
⇒ I1-1I = √2
or, If(i)I =√2
Hence, the value of If(i)I for f(x) = 1 -x is√2.
Answer:
Power is the rate at which energy is put into, or taken out of, a system. For example, a 500 Watt halogen light uses 500 Joules of energy every second.
There are two common units of power, the Watt and the Horsepower. This page will help you to convert between them.
